Pneumatic Wafer Butterfly Valves

Pneumatic wafer butterfly valve consists of rubber seal, valve plate (made of carbon steel or stainless steel) and valve stem. Applicable temperature is 80~120℃. It is widely utilized in food, pharmacy, chemical industry, petroleum and other industries to regulate flow or closure medium.
 
Characteristics of Pneumatic Wafer Butterfly Valve
1. Novel design, unique structure, light weight, rapid open and close
2. Small torque, convenient operation
3. Can be install in any position and it is convenient maintain.
4. Seal can be replaced and realize bidirectional sealing and zero leakage.
5. Aging resistance, corrosion resistance and long service life.

Actuator 
Pneumatic wafer butterfly valve utilizes GT pneumatic actuator, having double-acting and single-acting (spring reset). It is drove by gear, safe and reliable. Large diameter valve utilizes AW pneumatic actuator. It has reasonable structure, large torque output, double-acting and single-acting.
1. Gear dual piston, large output torque, small volume
2. Cylinder, made of aluminum gold, has light weight and beautiful form.
3. Manual handle can be installed on the top or at the bottom.
4. Gear connection can regulate opening angle and rated flow.
5. Actuator can ba attached with electric signal indication or other attachment to realize automation.
6. ISO05211 standard connection plate makes the production installation and change more easily.
